BleepingComputer.com: Dual boot Win XP from external hard drive?

I have an external SATA drive that was installed on a laptop and used Win XP. I have a new laptop with Win Vista but the software I use for work will not function with Vista. Am I able to set up the laptop to boot into Win XP from the external drive, and how?
Thank you!

-need to get back to work!

Hi there,

It's possible , but not officially supported by Microsoft as it involves modifying the Windows XP install CD. Please do so at your own risk.

Thank you for that information.
I know an alternative would be to create a partition and install it on the Vista hard drive. However, when I attempt to "shrink volume" I am only given 352MB of available shrink space. How do I free up more space here? I have 67GB free, 80GB used.
Thank you!

Hi rikilynn,

Here's a tutorial on how to deal with insufficient volume shrink space: http://www.howtogeek.com/howto/windows-vis...quacy-problems/

And here are a couple of guides for how to set up a multiboot system:

Install more than one operating system (multiboot)
